' TYPE-Warten@ MAcHINn Y' residentfof Owensboro, in the countyl of Daviess' and State of Kentucky', have in.v

vented certain new and' useful- Improvements in Type-Writing" Machines; and I do hereby declare the following to be a-.full,

clear, andfexact description of the invention, such as will enableA others skilled in the art to .which it appertain'sto make and use j j the same.

This invention relates to improvement-s in typewriting machines and more particularly to ribbon mechanisml therefor,- one object of the inventionbeing to so. construct ribbon mechanism' that the automatic shifting `of the ribbon shall be accurate and sure and so that the normal feeding ofthe r1b-l bon shall be uniform.

l A further object is to rovide ribbon operating and shifting mec anis'mwhich shall` be simplein` construction, comprlsing a comparatively small number of parts and which .j j Shall not be liable to get outof,Y order- With these objects in view,.the'invention consists in -certai'n novel features*V of con-v struction and combinations of parts as vhereinafter.. set forth `and pointed out .1n the claims. i

j In'theaccompanying drawings, Figure 1 is a longitudinal sectional view of a type'- writing machine embodylng my improvements.- Fig. 2is a front elevation, partly in section, showing the ribbon mechanism, and Fig. 31 is a' view-partly'in plan and partly in section showin theribbon mechanism.

` llrepresents "the` frame 'of the machine in the upper portion of which` a platen 2 1s located and mechanism .is yprovided for moving a vstrip; 3 of paper step-by-stp in front of @this platen: This paper feeding' 4.nriiechanism forms vno partvof the invention herein described and claimed and a detail.

explanation of the same is unnecessary. It

might be stated. however that the paper feeding mechanism is .connected with and operated-by the movements of a universal bar 4, the latter beingactuatedby arms 5 on key levers 6.

The type bars 7 of the machine are pivotally mountedfina notched bar 8 and connected at their lower ends with the key leverarms 5. j

Two vertical shafts 9 are mounted in the framework and u on the upper `ends of Specicaticn otyIvetters Patent. i Application med Marqh 11, 1913. serial No. 753,631.

bars' land the the ribbon 11 is guided., from one reel to 'the other. andbetween thzf type ofthaitypework for the accommodation of pawls 18,5, said pawls being pivotally connected with .the luniversal bar 4.- and, .passing between said guides, engage the ratchet lwheels 16.

the ribbon feed.

L-shaped levers 20 are pivotallj7 connected at their upper ends toa bar or rail 21 of. the framework and the approximately horizontal arms of theseL-shaped levers project under the respective pairs ofdo'gs or -pawlsl8-119,-said arms 22 being vertically movable in slotted guides22a secured to the guides 17. A longitudinally movable shift bar 23 is mounted in the framework above the ratchet' devices hereinbefore described v and provided with an. arm 24 which projects K through a slot 25 in the top of the frame- `work and terminates 4in position Vto be grasped by the 'dperaton The ends of the shift bar 23 are pivotally connected with the L-shaped levers 20, so that vvhen'said shift bar is moved 'longitudinally in one direction, one of ,the 'L-shaped' levers 20 will be operated to cause its horizontal member 22 to raise one pair of dogs or. pawls 18-19 out of engagement with thev ratchet'wheel with which they coperate, and to permit the horizontal member of the other L-sh'aped lever todesccnd and allow the 'other pair of dogs or pawls 18-19 to engage the other ratchet wheel. The machine frame is made with a hollow-member 26vwhich receives a spring-pressed plunger 27 to bear against the shift bar and hold itin the position to.l

which itv may be moved,vthe tension of the spring 28 for this plunger being adjustable by means of a screw 29.

I vhave above described the .devices means of which the direction vof feed of the inking ribbon can beshfted manually and Patented May 26, T1914.

j platenby meanso f vsu'ita le' guide rolls12. A beveledpinion 1 3 is 'se- 415 mountedinthe-framework. -The shafts 15 are disposedin'axial alinement with ea'clil vother but are independently operableaiid toA each of said shafts a ratchetwheel 16' is se cured. .Guides 17 are provided in the frame-l I will now proceed to explain the devices whereby the shifting of the inking ribbon is automatically effected.

Each ribbon reel is provided with a hub 30 which depends below the reel as clearly shown in Figs. 1 and 2. Each of these hubs is made with a recess 31 which is normally spanned by spring actuated hinged section 32 the spring tending to open this hinged section when the ribbon shall have become exhausted from the reel as shown at the right hand side of Fig. 3, but when ribbon is on the reel, the hinged section 32 willbe closed and' held so b y the ribbon as shown at the left in Fig. 3. L-shaped arms 33 are pivotally attached to the framework and in the free ends of the short members of these arms, wheels 311- are mounted and adapted to run on those portions of the sleeves or hubs 30 which depend below the ribbon reels,- such engagement of the wheels 34 with the sleeves or hubs 30 being insured by means of spring pressed plungers 35. Arms 36 project upwardly from the shift bar 23 and their upper ends are disposed 'between the long members of the L-shaped arms 33 and the hubs 30. When the inking ribbon shall have become exhausted from one ofne ribbon reels, the hinged section 31 of the hub 30 will be opened by the action of its spring and the springpressed plunger QT will operate to cause the roller 34 carried by the L-shaped arm 33 to move in a direction to enter the recess in said hub. The roller 34 on arm 33 will first engage the hub 30 at one edge of the recess 31, and the pressure exerted against said arm by the spring-v pressed plunger 35, will causethe reel-hub to be positively moved sufficiently to insure the entrance of the wheel 34 into recess 3l. Such movement will permit the arm 33 to engage one of the arms 36 of the shift bar 23 and move the latter longitudinally to operate the L-shaped lever 20 in the manner above explained to disenga e one pair of dogs or pawls from one rat het wheel and permit the other pair of dogs or pawls to engage the other ratchet wheel.'

It is! apparent that when the key levers are operated, the universal bar 4 ,will be actuated to loperate the dogs or pawls 18 and thus Cause' motion-to be transmitted to one or the other of ratchet wheels 16 and to one of the ribbon reels and that when the shifting devices are operated either manually or automatically,-motion will be transmitted to the other ribbon rcel for moving the ink ing ribbon in the reverse direction.. i

Having fully described my invention what l A Witnesses:

`respective L-shaped arms,

machines, the Acombination with two shafts, alining shaft sections disposed at right angles to said shafts, and gearing between said shaft sections and said shafts, of a ratchet wheel carried by each shaft section, a movable universal bar, dogs or pawls carried by said universal bar and adapted to engage the respective ratchet wheels, other dogs pivoted to a Xed support and adapted to engage the ratchet Wheels, pivoted arms projecting ander the respective pairs of dogs, and a longitudinally movable shift bar pivotally connected with the respective arms.

2. In ribbon mechanism for typewriting machines, the combination with two shafts,

ribbon reels thereon, shaft sections disposed der-one of said dogs or pawls, alongitudinally movable shift bar pivotally connected with said L-shaped arms, and an operating arm projecting from said shift bar.

In ribbon mechanism for typewriting machines, the combination with two shafts, alining shaft sections geared to said shafts, and ratchet wheels secured to said shaft sec tions, of a movable universal bar, dogs carried by said universal bar and adapted to engage the ratchet wheels, Lshaped arms pivotally supported 'at one end and 'projecting at their other ends under said dogs or pawls, a longitudinally movable shift bar pivotally connected at its ends with the ribbon reels mounted on the first mentioned shafts and each provided with a hub having a-recess and projecting beyond vsaid reel, a spring actuated hinged section for each hub for spanning the recess therein, pivoted arms having rollers to run on the projecting portions of said'hubs and adapted to enter the recesses in latter when the hinged sections thereof are open,l and arms projecting from the shift bar in position to be engaged by one or the other of said last mentioned pivoted arms when the same is permitted to move so as to allow its roller toenter one of said sleeves or hubs.

In testimony whereof, I have signed this specification in the presence of two subscrib-l ing witnesses.
